brainliest is appreciated
#1
Work done is given by
here we know that
F = 157 N
d = 14.5
now from the above formula
#2
By energy conservation
Initial total potential energy of egg = final total kinetic energy of egg
#3
By momentum conservation we know that
#4
by momentum conservation we know that
let direction of velocity of Jay Z car motion is positive direction
now we will say
Yes Jay Z is overspeeding as his speed is more than speed limit
#5
Tension force in the string will be centripetal force
so here we can say
here we know that
m = 0.63 kg
v = 7.8 m/s
R = 0.23 m
First you do 2.5 n-m / 2 kg-m2
This equals 1.25 rad/s^2
Then multiply rad/s^2 by 10 because of the amount of seconds
This equals 12.5 rad/s^2
Then do this following equation : (1/2)Iwf^2
Do (0.5) 12.5 * 12.5 * 2
This equals 156.25 J (meaning that the answer is C: 156 J)
Answer:
Convert all the times to either hours or seconds
Explanation:
One time unit is in hours, and the other is in seconds. In order to do the math, the units need to be the same. So you either need to convert hours to seconds, or seconds to hours.
